Cylinder lenses are characterized by one of the surfaces being cylindrical (as opposed to a typical spherical shape), while the other is typically flat.
The cylindrical surface of a cylinder lens can be both convex or concave. The unusual shape changes the beam transformation: a point subject is projected into a line image, as opposed to a typical point image.
Cylinder lenses find its use in many different applications, where nonlinear beam shaping is necessary. Example uses include illumination systems for line detectors, slotted diaphragms in spectroscopy and creation of pattern indicators for scanners in medical techniques.
